vs
Spark plug OEM BMW or OEM Subaru
Reviews
The most expensive proposition was a new windshield, but your particular insurance could solve that. Spark plug replacement was a surprise as far as cost is concerned. I've routinely changed the oil and cvt fluid once. No other maintenance issues. I love the car. Incredible roominess in the cabin and very capable offroad when needed.
Pros: no other maintenance issues, capable offroad
Cons: expensive windshield, costly spark plug replacement

Subaru Forester
Mileage: 98000 km
I did absolutely nothing apart of spark plugs and oil change . I had E90, 188k km, 330d until it meet it's end when I crash it to railguards. it never showed me any lights or anything so I would say around 60-80$ tops.
Pros: reliable, no warning lights
Vehicle:
BMW
Mileage: 188000 km
I almost went 200000 km on my bmw between spark plug changes, and the motor runs so much better after. My fuel economy almost doubled, and performance was a night and day difference
Pros: motor runs better, fuel economy doubled

BMW

My 2015 outback has 140k miles. I just did spark plugs and belt, brakes. That's the only maintenance I've ever done other than tires and batteries.

Subaru forester. Mine is a 15. Comfortable, decent gas mileage, able to seat 4 with stuff in back. Kayaks fit on roof. AWD helps in rain and snow. Easy to do basic maintenance, but spark plugs SUCK.
Pros: comfortable, decent gas mileage
Cons: spark plugs SUCK
Vehicle:
Subaru Forester
I did my spark plugs on my 335i f30 and I can say one thing. $400 for labor on spark plugs is treason. Shit should take those "experienced" mechanics maybe an hour.
Cons: expensive labor
Vehicle:
BMW
I just completed my first spark plug change on my G20 330 at 40k miles. Three of them especially Cylinder 1 came out "wet" and I'm unsure if it's oil.
Cons: wet spark plugs
Vehicle:
BMW
Mileage: 64373 km
I now dread doing spark plugs. Something that’s super easy to do on most 4 cyl cars is a PITA doing on my ej25.
Cons: spark plugs difficult to replace
I dug factory installed spark plugs out of my recently departed E90... they looked like something from the stone age. 19 year old car, and from what I could tell, never had the plugs changes.
Cons: old spark plugs
Vehicle:
BMW
Cylinders 1-3 were misfiring. They couldn't get the spark plug out of cylinder 3 because the other dealership had over tightened it. They had to get a special tool to remove it. The tool BROKE because apparently it was so overtightened and mis-threaded. They finally got it out yesterday and sent the cylinder to the machine shop to get the head off. I just got word that there is a hole in the piston and the valve head is completely gone. They are saying now that it has nothing to do with the spark plug being overtightened. He asked about driving through water, and road conditions. It was a dry day. Not an issue. They said I need a new motor at this point.
Pros: spark plug removed, new motor needed
Cons: overtightened spark plug, broken tool, hole in piston, valve head gone
